[SOLVED] Are My Temps Too High?

I recently built a new PC with a Ryzen 5 3600X cooled by an Arctic Liquid Freezer II 240 AIO. My idle temps on the CPU are around 46C and I get full load temps (with Cinebench or video rendering) temps of 83C while the CPU clocks down to 4.08 GHz even with the front panel off (the radiator is an intake). Is something wrong here?

I've already tried reseating the cooler several times and I've noticed that the cooler isn't fully covered with thermal paste while the CPU is. Is that the problem?

Just a recap:
Arctic LF 2 240
Ryzen 3600X
Phanteks P400(non-A)
Now then...

1)You made sure the paste spread and covered the cpu IHS fully? The little in the middle application tends to not be too effective on Ryzen due to the multiple chiplets beneath.

2)Arctic LF 2 + P400.
Goes without saying that since the only option is to mount it up front, you're forced to mount the cooler right up against a rather hard airflow restriction.
The best way to maximize airflow here is to position the fans behind the radiator, pulling air inside the chassis. Just a reminder of which way air comes in and out:

3)About the LF 2: Boxed unit ships with pump and fans managed by single PWM splitter.
"While the Liquid Freezer II 280’s 140mm fans are factory installed and managed with the same PWM power that controls the pump and auxiliary fan, we opted to disconnect the fans and run them independently for our tests, allowing for independent PWM cooling fan management while the pump remained powered at 100%."
If you want to control the fans and pump separately, you'll have to connect the fans directly to the motherboard, otherwise, all 3 will operate on a preset PWM curve.
Fractal Design's Celsius does something similar.

Maybe it's thermal paste? Try thermal grizzly kryonaut. I'm not sure what that's all about, but it sure does defeat the purpose of having a liquid cooler when a good air cooler could cool better than that!

The one I used is Arctic MX-4 that I bought early this year so it could possibly be a little old. I'll try that

Ya seems alittle high for a cooler that got a pretty good review.

What are you using to monitor your temps?
What are your fan and pump speeds?
I used HWMonitor and AMD Ryzen Master to check temps (not at the same time).
My fan and pump speeds are set to 40% at 40C, 80% at 65C, and 100% at 80C.
 
Hmm
Can't doubt the temps then.

I used Mx-4 and the changed right back to what I was using for yrs which is Thermaltake tg-7.
If you have a Best Buy near you can try a tube for approx $8.00
The also carry the Corsair pastes also for alittle more.

What case do you have? And how many other fans do you have?
Fan Config ?

I have a Phanteks P400 for my case and I'm using the two included fans as exhausts. One on the rear and one on top. The radiator fans are used as intake on the front.

Is it? I know MX-4 won best thermal paste of 2019 I think so I'd guess it's better and I don't think it's a red herring. It does transfer heat faster but we all know it only ends with a 1-2-3C difference.
It's a part of the whole picture. The one with higher W/mK isn't always better.
I mean, TG Kryonaut doesn't exactly wipe the floor with those 2 pastes either.

Aww, who am I kidding? Some manufacturers don't even bring it up.

wait what?!? I thought the grizzlies was best I listen to bad propaganda?
It doesn't really matter all that much... the purpose of paste is a bridge, and any direct cooling benefits are so minor.
Thermal Grizzly is overhyped to the moon and it doesn't 'stomp' the likes of MX-4... plus, it has some QC issues: there's fakes out in the market... WTH.

To add to the above, I recently ordered TG Conductonaut - first time ever ordering it, and in the package, there's a little card with a code on it that you enter online TO VERIFY IF IT'S LEGIT...
What a joke.
 
OK good but it's not so much as the tubes are down as the Pump isn't the highest point in the system to keep the air bubble in the top of the tank.

Going back to the beginning he stated
"I've already tried reseating the cooler several times and I've noticed that the cooler isn't fully covered with thermal paste while the CPU is."

Maybe too convex on the coldplate?????
